Vacuum Packaging Device With Integrated Cutting Notch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum packaging devices require additional tools or manual tearing, which can lead to contamination and inconvenience when opening sealed packaging sheets.
Innovation Solution
A vacuum packaging device equipped with a cutting unit that forms a tearing notch on the packaging sheet, allowing for easy opening without external tools, using a cutting member and driving part to cut the sheet, either manually or automatically via air pressure changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a cutting tool is not provided in the vacuum packaging device, then the device structure remains simple, but the packaging sheet cannot be easily opened and requires manual tearing which causes contamination
Solution Approach 1:
The patent combines the cutting function with the vacuum packaging device by integrating a cutting member into the packaging unit. This merging allows the device to perform both vacuum packaging and opening operations, eliminating the need for separate cutting tools while preventing food contamination during opening.
Solution Approach 2:
The cutting member creates a predetermined tearing notch on the packaging sheet during the vacuum packaging process. This preliminary action prepares the sheet for easy opening by establishing a controlled weak point, allowing users to open the packaging safely without manual tearing that could contaminate the food.
2Ease of operation
If manual tearing is used to open the packaging sheet, then no additional tools are needed, but the tearing process is difficult and causes food contamination
Solution Approach 1:
The cutting member creates a predetermined tearing notch on the packaging sheet during the vacuum packaging process. This preliminary action prepares the sheet for easy opening by establishing a controlled weak point, allowing users to open the packaging safely without manual tearing that could contaminate the food.
Solution Approach 2:
The cutting member acts as an intermediary tool that is integrated into the vacuum packaging device. It performs the cutting action automatically during packaging, creating a safe opening path that prevents direct manual contact with the food during the opening process.
3Ease of operation
If an additional cutting tool is provided, then the packaging sheet can be opened easily, but the device complexity increases and requires additional components
Solution Approach 1:
The patent combines the cutting function with the vacuum packaging device by integrating a cutting member into the packaging unit. This merging allows the device to perform both vacuum packaging and opening operations, eliminating the need for separate cutting tools while preventing food contamination during opening.
Solution Approach 2:
The vacuum packaging device is designed with multi-functionality, incorporating both vacuum packaging and cutting capabilities. The cutting member can be activated during the packaging process to create tearing notches, allowing the single device to perform multiple functions without requiring separate tools.
4Reliability
If a cutting member is integrated into the vacuum packaging unit, then the packaging sheet can be opened safely without contamination, but the device structure becomes more complex
Solution Approach 1:
The patent combines the cutting function with the vacuum packaging device by integrating a cutting member into the packaging unit. This merging allows the device to perform both vacuum packaging and opening operations, eliminating the need for separate cutting tools while preventing food contamination during opening.
Solution Approach 2:
The cutting member is designed to operate automatically during the vacuum packaging process, utilizing the existing packaging mechanism to create tearing notches. This self-service approach allows the system to prepare the packaging sheet for opening without requiring separate manual intervention or additional complex operations.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables simple and safe opening of sealed packaging sheets by forming a predetermined tear notch, preventing contamination and improving user convenience.
Implementation Method 1
the driving part may further include an elastic member installed in the first supporting groove and elastically supporting the pressing member, and the elastic member may apply elastic force reversely to the pressing member when the pressing member moves by the pressing force
Implementation Method 2
the moving member may move together with the cutting member by a change in air pressure in the housing caused by air suction or air discharge by the vacuum pump of the vacuum packaging unit
